By default, the maximum number of event files stored on the collector in the event of a WAN link failure between the collector and the supervisor is 10.000. This value can be changed in the collector.properties file by modifying the parameter max_event_files_to_store. References: Fortinet NSE 7 - Advanced Analytics 6.3 Exam Description, page 13

When a user is off-net, meaning they are not connected to a network where a FortiSIEM collector is reachable, then UEBA events will be cached locally by the agent if it cannot upload them to a FortiSIEM collector. The agent will store up to 100 MB of events in a local database file and try to upload them when it detects a network change or every five minutes.

You can invoke an integration policy on FortiSIEM rules by configuring the Notification Policy settings. You can select an integration policy from the drop-down list and specify the conditions for triggering it. For example, you can invoke an integration policy when an incident is created, updated, or closed. References: Fortinet NSE 7 - Advanced Analytics 6.3 Exam Description, page 9

The syntax that will register a collector to the supervisor is phProvisionCollector --add . This command will initiate the registration process between the collector and the supervisor, and exchange certificates and configuration information. The parameter is the IP address of the supervisor node.

 The SQLite databases that are used for the baselining are stored on Disk3 of the FortiSIEM server. Disk3 is also used for storing raw event data and CMDB data.

The natural_id value identifies the collector in the FortiSIEM system. The natural_id is a unique identifier that is assigned to each collector during the registration process with the supervisor. The natural_id is used to associate events and performance data with the collector that collected them.

FortiSIEM allows EPS bursting to handle event spikes without dropping events or violating the license agreement. EPS bursting means that FortiSIEM will let you burst up to five times the licensed EPS at any given time, provided it has accumulated enough unused EPS from previous time intervals.

Tactic is what an attacker hopes to achieve in the MITRE ATT&CK framework. Tactic is a high-level category of adversary behavior that describes their objective or goal. For example, some tactics are Initial Access, Persistence, Lateral Movement, Exfiltration, etc. Each tactic consists of one or more techniques that describe how an attacker can accomplish that tactic.

The processes associated with Machine Learning/AI on FortiSIEM are phFortiInsightAI and phAnomaly. phFortiInsightAI is responsible for detecting anomalous user behavior using UEBA (User and Entity Behavior Analytics) techniques. phAnomaly is responsible for detecting anomalous network behavior using NTA (Network Traffic Analysis) techniques.

The incident from FortiSIEM shown in the exhibit is a brute force attack on a FortiGate device. The remediation option available to the administrator is to run the block IP FortiOS 5.4 action, which will block the source IP address of the attacker on the FortiGate device using a firewall policy.
